WASHINGTON: The White House was placed on lockdown late on Tuesday after a person attempted to jump over a bike rack used as a barrier along the north fence of the mansion where President Donald Trump lives and works, according to the US Secret Service's official Twitter account.

Security had been tight for Turkish President Tayyip Erdogan's visit earlier in the day, as protesters gathered in front of the White House. Erdogan, however, left before the lockdown.

"We've had a great relationship and we will make it even better," Trump had said in the joint appearance with Erdogan. His Turkish counterpart, on the other hand, commented that his visit would "mark a historical turn of tide," and hailed "outstanding relations" between the nations.

The bike rack runs alongside the North Fence Line of Washington, D.C.'s Pennsylvania Avenue – a street linking White House to the Capitol.
